Description

For both <style> and <link>, the "Create a CSS style sheet" algorithm is called with the CSS rules "left uninitialized". Neither of them seem to pass off the source text to the CSS specification.

<style> defines the concept of "style data", but never seems to indicate how this gets wired up to create CSS rules. <link> doesn't even do that.

Is this taken care of behind the scenes in some way by CSS? If so, we should add a note. If not, we've got a pretty glaring spec hole.

I guess at some point someone should call the algorithms in https://drafts.csswg.org/css-syntax/ ? /cc @tabatkins @SimonSapin
